产品型号: 67-7319-74
产品品牌: RIKEN KEIKI Co., Ltd.
功能
- It can be used for explosion prevention control and constant monitoring of hydrogen gas in research and laboratory.
- Hydrogen gas concentration is displayed by two methods, bar meter and digital.
- The name of the hydrogen gas changes to three colors to indicate the detection status, so that the detection status can be visually confirmed from a distance (three colors: normal: green, 1st alarm: orange, 2nd alarm: red).
- The indication alarm unit (model: GP-6001) adopts an independent unit for easy installation.
- The two-stage alarm function enables the gradual management of gas alarms.
- Adoption of maintenance mode function makes it possible to shut off external alarm during maintenance.
- Gas detection part: Compact and lightweight, pressure-resistant explosion-proof structure (explosion-proof, etc., so it can be used in hydrogen atmosphere), dustproof and waterproof structure (protection grade: equivalent to IP 67), and can be installed in harsh environments.
